DISPLAYING OR ADVERTISING APPARATUS.

Specification of Letters Patent.

Patented Nov. 11, 1919.

Application filed September 6, 1919. Serial No. 322,184.

To all whom it may concern:

Be it known that 1, JAMES HoLLINes- WORTH CLEGG, a subject of the King of England, and residing at West Kirby, in the county of Chester, England, have invented Improvements in or Connected with Displaying or Advertising Apparatus, of which the following is a specification.

This invention has reference to displaying or advertising apparatus of the type wherein gaslight is used and movement of parts are obtained by a bellows or like type of motor by the mechanical energy of the gas, that is, by the pressure under which it is normally supplied; and the gas is adapted to be supplied to and cut off from the lamp or light by the action of the gas operated bellows -motor itself, whlch through a running ball or device inside the bellows, which is caused to move to and fro by the movement of the bellows, alternately close the gas supply and open the delivery to the lamp or light, and open the gas supply and close the delivery.

The object of the present invention is to provide improvements in this type of advertising or displaying apparatus by which better or more advantageous effects are obtained, and the apparatus in itself is rendered more certain, and proof against derangement, and consequent defective action.

In apparatus of the kind referred to, according to this invention, the valves are disposed as stated, within the bellows, say on the inside of the upper cover or roof, are arranged, one at each end of a runner way, and work in connection with the gas inlet and outlet, and the ball runner is supported by and runs to and fro on two bars below the gas inlet and outlet pipes and from the bellows-which say is of the ordinary hinged type-so that one valve in one position of the bellows is acted on by the runner and closed, and the other is free to open, and vice versa.

The valves may be of the hinged flap type, disposed directly opposite each other, and one Or both may have an arm which will be acted upon by the ball or runner so as to positively open the valves, or by suitably being weighted.

The action of the bellows motor, in one arrangement, actuates a barrel or frame carrying a plurality or series of pictures or devices, and having within it, a gas lamp or lamps which illuminates and renders visible or conspicuous the same, which are the things it is desired to display or advertise.

The apparatus is illustrated in the annexed drawings, in which Figure 1 is a sectional elevation showing the bellows motor extended; Fig. 2 is a sectional elevation showing them collapsed; and Fig. 3 is a plan in section.

Referring to the drawings, 1 represents the upper movable member of the bellows apparatus, and 2 the lower member, and 3 the inclosing rubber or flexible expandible casing or skin; the two parts 1 and 2 being hinged together at 4 at one end.

5 is the gas inlet branch, and 6 is the gas outlet branch, these two branches and conduits being connected to the valvular apparatus by rubber or flexible tubing 7 and 8, respectively.

The valvular controlling device is attached to the inside surface of the upper movable member 1 of the bellows, and con sists of two end plates 9 and connecting bars 10, the lower pair of which form a guide or track for the running valve operating ball 11.

Just within the end frames 9, the ends of the metal tubular terminals 12 and 13 on the inlet and exit tubes, extend; and in connection with the open ends of these, are the inlet valve 14, and discharge valve 15, both of which are hinged below as shown; and the latter is provided with a tail 16 forming it into a bell crank form of valve, which is operated upon by the runner ball 11 as it moves to and fro along the track bars 10. The valve 14 may also have a similar tail.

When the bellows is filled with gas by its entry through the pipe 7 and valve 14, the track bars 10 of the ball 11 are inclined so as to cause the ball to move away from the valve 15, and move on to the valve 14 as indicated in Fig. 1; so that in this condition the gas inlet valve is closed, and the gas discharge valve is open, and the gas will pass from the bellows to the gas lamp or lamps, or burners, and burn there, so as to render visible or throw into prominence advertisements or matters to be displayed. The gas lamp or lamps or burners may have a bypass or the like on them, so as to ignite the gas each time the apparatus is operated; or, a certain quantity of gas may always be supplied to the burner when the bellows is filling, as to be just sufiicient to lreep the lamp or burner alight, while when the discharge valveis opened, full illumination by the lamp is furnished.

The gas on the opening of the discharge valve, passes away to thedisplay apparatus by the pipe 8 full bore, and the bellows e01:

lapses by its own weight, or suitable weights being placed on the upper movable member 1; and when the gas has been consumed the ball track bars 10 Wl-ll bB tilted in the oppositedirection, as seen in Fig. 2, and the ball will move away from the'inletvalve 14c, and on to the outlet valve 15, opening the former and closing the latter, when thevlamp or burner above described will be, wholly or partially lowered or extinguished.

, j The action of the bellows motor may actu- 1 1 ate a barrel orframe carrying a plurality of pictures or devices, and having within it a gas lamp .or lamps or burners referred to which illuminates or renders visibleorcom spicuous the pictures-or devices, which are the things which it is desired to display or while it is being rotated or moved, the gas will be cut off to the lamp or light, except a certain amount supplied through a by-pass.

hat is claimed is A gas light controlling mechanism comprising a bellows, brackets mounted on the movable portion of the bellows, an inlet and an outlet pipe carried in the brackets, the ends opening directly into the interior of the bellows, and being oppositely disposed, a trackway mounted in the brackets, a ball carried thereby, a valve hinged to one bracket for closing the inlet pipe and a valve hinged to the other bracket for closing the outlet pipe, and having an arm extending therefrom, whereby, in one position, the ball will hold the'outlet valve closed while the inlet valve is open allowing gas to fill the bellows, and in the other position the ball will hold the inlet valve closed while the outlet valve is open, and the valve having the arm thereon will hold the ball against movement on the trackway until the weight of the ball overcomes the pressure tending to hold the valve closed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
